# 阶段 1：定义 go-judge 来源
FROM criyle/go-judge:latest AS source

# 阶段 2：构建实际运行环境
FROM ubuntu:24.04

# 设置环境变量
ENV TZ=America/Vancouver
ENV DEBIAN_FRONTEND=noninteractive

# 修改源 (可选)
RUN sed -i 's@//.*archive.ubuntu.com@//mirrors.aliyun.com@g' /etc/apt/sources.list.d/ubuntu.sources && \
    sed -i 's@//.*security.ubuntu.com@//mirrors.aliyun.com@g' /etc/apt/sources.list.d/ubuntu.sources

# =========================================================
# 【修改点 1】安装 gcc-14 和 g++-14
# Ubuntu 24.04 源里自带 gcc-14，直接安装即可
# =========================================================
RUN apt-get update \
    && apt-get install -y --no-install-recommends \
    locales \
    gcc-14 g++-14 \
    python3 pypy3 openjdk-21-jdk \
    vim curl \
    && rm -rf /var/lib/apt/lists/*

# =========================================================
# 【修改点 2】设置 GCC 14 为默认编译器
# 使用 update-alternatives 将 /usr/bin/g++ 指向 /usr/bin/g++-14
# =========================================================
RUN update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-14 100 \
    && update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-14 100 \
    && update-alternatives --install /usr/bin/cc cc /usr/bin/gcc-14 100 \
    && update-alternatives --install /usr/bin/c++ c++ /usr/bin/g++-14 100

# 2. 生成语言包 (解决 LC_ALL 报错)
RUN locale-gen en_US.UTF-8
ENV LANG=en_US.UTF-8
ENV LANGUAGE=en_US:en
ENV LC_ALL=en_US.UTF-8

# =========================================================
# 【核心修复】修复 Java 配置文件软链接问题
# 注意：JDK 目录名随架构变化，不能写死：
#   amd64 -> java-21-openjdk-amd64
#   arm64 -> java-21-openjdk-arm64 (Apple Silicon 等)
# 这里用通配符动态解析实际目录，并额外建立 amd64 兼容软链接，
# 保证 lib/judge.ts 中硬编码的 java-21-openjdk-amd64 路径
# 在 arm64 镜像上同样可用。
# =========================================================
RUN JDK_DIR=$(ls -d /usr/lib/jvm/java-21-openjdk-*) && \
    cp -rL "$JDK_DIR/conf" /tmp/java-conf && \
    rm -rf "$JDK_DIR/conf" && \
    mv /tmp/java-conf "$JDK_DIR/conf" && \
    if [ ! -e /usr/lib/jvm/java-21-openjdk-amd64 ]; then \
        ln -s "$JDK_DIR" /usr/lib/jvm/java-21-openjdk-amd64; \
    fi
